子宮体癌在女性生殖器官恶性肿瘤中的发生率,仅次于子宮頸癌。二者发生率之比較,以往資料是每7-8个子宮頸癌比1个子宮体癌;但近年的文献統計,其比率已变为2-3:1以下。虽然統計数字随研究机构有所不同,但与二个原因有关系,即人类寿命增长(子宮体癌見于老年妇女)及子宮頸癌之早期診断。 The incidence of uterine body cancer in female genital malignancies, second only to cervical cancer. The incidence of the two compared to the past data for every 7-8 cervical cancer than a uterine body cancer; but recent literature statistics, the ratio has become 2-3: 1 or less. Although the statistics differ from those of research institutes, they are related to two causes, namely, an increase in human lifespan (early detection of endometrial cancer in older women) and cervical cancer.
